With the same products being used around the globe, it is important to adapt products to local markets particularly where the original comes from a different culture and language. Not only does the product require adaptation, but the technical guides and Help system associated with those products require adaptation. The adaptation of a product includes shortening UI descriptions, creating UI's with a global appearance, and so on.

The abbreviations for globalization, localization, and internationalization are based on taking the first and last letters of the word, using the lower case form, and the number of letters in between: g11n, l10n,and i18n respectively.

Considering the global playing field, for any entity to be successful, product and documentation must be geared to any culture. For example, Microsoft was one of the first companies to globalize its products so that sales in foreign markets would excel. Had Microsoft not incorporated g11n and l10n into its development process, translation and use of their products may not have been successful; in fact, product sales may have failed. When writing with localization in mind, it is easier for users to understand processes and procedures, and products are more widely accepted when they (and the documents that accompany them) are developed without cultural bias.

Another important reason to write documents with localization in mind is that it reduces the cost of translation. In some cases, a single word can cost USD .25 to .33 to translate. Using a localization technique called "Simplified English" reduces the amount of words used, thus the cost of documentation.

Simplified English (or Plain Language) is one of the key elements to writing for localization. It incorporates the use of simple terms, grammar, and punctuation that can be easily and accurately translated into different languages (not to mention, it is less costly). In addition, global syntax, global art, jargon, gender specifications, and so on all play a role in writing for localization.
